Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly 5G NR, face challenges in optimizing data rate, latency, and reliability for various use cases, and there is a need for improved simultaneous transmission capabilities in multi-panel operations to enhance network performance.
Innovation Solution
The method and apparatus for Simultaneous Transmission with Multi-Panel (STxMP) operations involve a User Equipment (UE) and Base Station (BS) configuration that includes receiving and transmitting Physical Uplink Shared Channel (PUSCH) signals using multiple SRS resource sets, with specific DCI formats and CORESET configurations, enabling simultaneous transmission on multiple panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multi-panel simultaneous transmission is implemented, then data rate and network performance are improved, but device complexity and configuration complexity increase
Solution Approach 1:
The patent segments the transmission configuration by introducing separate SRS resource sets for different panels, with each panel having its own SRI field in DCI. This segmentation allows independent configuration and management of each panel's transmission parameters, making the complex multi-panel system more manageable while enabling simultaneous transmissions on multiple panels to improve data rate
Solution Approach 2:
The patent adds a panel dimension to the existing single-panel transmission framework by introducing panel-specific SRS resource sets and panel identifiers. This dimensional expansion enables simultaneous transmissions across multiple panels without fundamentally redesigning the entire system, thus improving productivity while controlling the increase in complexity
2Productivity
If multiple SRS resource sets are configured for different panels, then simultaneous transmission capability is improved, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent creates universal SRS resource set configurations that can serve multiple panels, with each resource set capable of being associated with different panels through panel identifiers. This multi-functionality reduces signaling overhead by avoiding redundant configurations while still enabling simultaneous transmissions on multiple panels
3Reliability
If separate DCI fields are added for each panel, then transmission precision and reliability are improved, but DCI size and processing complexity increase
Solution Approach 1:
The patent applies local quality by adding panel-specific SRI fields only where needed in the DCI structure, rather than uniformly increasing complexity across all DCI elements. Each panel's transmission parameters are precisely controlled through dedicated fields, improving reliability while minimizing overall processing complexity

AI summary
A method performed by a User Equipment (UE) for a Simultaneous Transmission with Multi-Panel (STxMP) operation is provided. The method receives a configuration for multi-DCI based STxMP Physical Uplink Shared Channel (PUSCH). The method receives a Sounding Reference Signal (SRS) resource set configuration including a first SRS resource set and a second SRS resource set. The method receives first DCI in a first Control Resource Set (CORESET) and second DCI in a second CORESET. The method determines a size of a first field in the first DCI and a size of a second field in the second DCI based on the number of first SRS resources in the first SRS resource set and the number of second SRS resources in the second SRS resource set, respectively. The method transmits a first PUSCH and a second PUSCH scheduled by the first DCI and the second DCI, respectively.
